Si considera il problema della convezione naturale in un mezzo poroso tenendo conto - com'è nella realtà geofìsica - delle variazioni della viscosità con la temperatura. Si stabiliscono condizioni che assicurano la stabilità non lineare nella norma di \( L^{2} \) (stabilità in energia) nell'ambito del modello di Brinkman.
